Lowe’s complaint: Fencing not installed

I purchased fencing On January 12th to be installed. As of April 13th, I have spent over 185 minutes on the phone, that is 3 hours and 15 minutes doing work that Lowes should be doing for me. I found that working with customer service reps was to no avail because of their lack of knowledge. I paid upfront as required a total of $4402.13. I have been told by different associate my merchandise was received on this date or that date, yet no one can find my merchandise anywhere in the system. I was even called and told the fencing would be delivered between 12 and 4 one day this week, yet no one delivered the merchandise. I have run out of options, so I will be turning this over to legal next week. I will post on social media for all to avoid ordering or asking for installed goods from Lowes. The gentleman I spoke with today was very helpful along with a lady named Stephanie, back on the 22nd of March, the rest of the associates could care less about the customer.
